ABSTRACT


Purpose: To Evaluate Short Implants With Different Attachments For Assisting Partial Overdenture For Mandibular Kennedy Class I Cases.

Materials and Methods: 14 Partially Edentulous Patients Were Selected With Mandibular Bilateral Free End Saddle Having The Firs Premolars As The Main Abutments. Two Short Dental Implants Were Inserted At The Firs Molar Areas And Mandibular Implant Assisted Partial Overdenture Was Fabricated. Patients Divided In Two Groups 7 In Each. Group A: Partial Overdenture Was Retained By Ball And Socket Attachment To The Implants. Group B: Overdenture Retained By Locator. Clinical Evaluations Included: Gingival Index, Probing Depth And Implant/tooth Stability By Periotest, Radiographic Evaluation Was Done For Alveolar Bone Loss Around Implants And Abutments At Time Of Denture Insertion, 6 Months, 12 Months And 18 Months. At The End Of The Study The Data Were Collected, Tabulated And Statistically Analyzed.

Results: There Was No Statistically Significanc Difference Between The Groups As Regards To Clinical Evaluations Of Gingival Index, Probing Depth And Implant/tooth Stability. However, Radiographic Evaluation By Digital Periapical And Panoramic Radiograph Showed Statistically Significan Difference Between Two Groups Regarding The Marginal Bone Loss Around Implant, Abutment Teeth.Conclusion. The Group Of The Implant Assisted Partial Overdenture Restored With The Locator Attachment Showed Better Effect On Bone Health Around The Placed Dental Implant And The Main Natural Abutment When Compared With The Other Group Of The Implant Assisted Partial Overdenture With Ball & Socket Attachment.
